KAR-700 - Hidden camera in my sister's room! Caught her masturbating until she loses control and pees herself - 5h 40m Special

The models aren't classic beauties or pretty girls, but that actually makes it feel more real. There's a certain 'ugly-cute' charm that's surprisingly arousing. Even though it's acting, she goes, 'Big brother, big brother,' and 'You smell like big brother,' while sniffing his underwear. It's like a 2D sister from an eroge. No one believes hidden-camera masturbation videos are real anymore, but it's so fantastical it might make you laugh. I rented it, but I think I would've been happy buying it.
